He suffered 10 stab wounds to the neck, chest and back, the state medical examiner’s report stated. The case is unsolved.

The killing took place in the 500 block of Willow Creek, in a quiet residential area on a Monday afternoon. An undisclosed amount of cash was taken from his wallet. His killer appears to have vanished.

"It’s mysterious,” his son said. "You wonder how that happens.”

Police and the Oklahoma State Bureau of Investigation haven’t given up on finding who killed Shaw. Investigators have planned a news conference today in support of the family’s wishes to keep the case in the public eye.

"At this point, it doesn’t seem like much is happening,” said his son, Jason Shaw. "We’re trying to keep it alive.”

Investigators have ruled out several early suspects spotted in the area near the time James Shaw was killed, OSBI spokeswoman Jessica Brown said.
